The Amry's 4th made this discovery recently, these are being dug up as we speak. 11 "van" style boxes were found buried to avoid detection. They also seized about 1000 pounds of documents from these labs as well. These were also found very close to an artillery manufacturing plant. I'm sure there will be more on this as the days go by.
There is some information on this and the plutonium found here.
